ARVAC MANUFACTURING CO., 0F CHICAGO, ILLINOIS.

UNIVERSAL JOINT.

Michigan, have invented certain new and useful Improvements in Universal Joints, of which the following is a specification.

Thisinvention relates to improvements in universal oints.

The main object of my invention is to is compact and at the same time strongand durable, and one m which the parts are simple and economical to .produce and easily .and quickly assembled and disassembled as occasion requires.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the. objects of my invention by'the'devices `and means described i'n `the following specification. clearly vdefined and pointed out inthe claims.

A structure which is a preferred embodiment of myl invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Figure I is a side view of a structure em- -i bodying the features of my invention', the

shafts lto be jointed being shown broken away.

Fig. II is a transverse section on a line corresponding to line' 2-2 of Figs. I and III, the journals being shown in full lines.

Fig. vIII is a longitudinal section on a line corresponding to line 3-3 of Figs. II and IV, the journal pin being shown in full lines. Y Fig. IV is-a longitudinal section on a line corresponding to line 4 4 of Figs. I, II and III. the journals being shown in full lines.

Fig. V is a detail section on a line correspoiiding to line 5-5 of Fig. II, showing structural details.

In the drawing similar reference chai'- acters refer to similar parts throughout the several views, and the vsectional views are taken looking .iii the direction of the little arrows at the ends of the section lines.

Referring to the drawing, l and Q repre sent the shaft sections to be coupled.

My improved universal joint comprises i. female shaft member 3 ha"ing a shank at adajred to receive the shaft Q. and a malev me er having a shank G adapted to rcceivc` the shaft l.. The female member is Specication of Letters Patent.

The invention is retreated-rei). 2o, rait.

preferably formed to` constitute-a casing,rv

member. The female member has' an internal cylindrical part or surface adapted to receive the annular journal member 8. T his journal member isprefer'alily spheri cally curved, as shown in Fig. V,so that 'it is an oscillating orworking lit within the cylindrical part of the female member. The

male member has a` spherically curved head 9 disposed within the annular journal member to oscillate therein and is preferably a working fit` therein.

The journals l0 for the journal member 8 are threaded into the female member 3 to engage the'bearings l1 of the journal member.` The journal pinl l2 for the male member is disposed through the journal member and the male member head 9 at right angles to the journals 10 and is preferably of such length that it is supported against longitudinal movement by the walls of the female member.

A bearing block 13 is disposed in-the end i of the male member to receive the journal pin, the block being member.

AThe flexible casing member l-Ll is secured to pressed into the male ythe end-of the female member bythe clamping ring 15,'the ring being secured by the screws 16, and to the shank of the male member by the clamp 17.

lVith the parts thus iiicased the joint may be filled with suitable lubricant and the bearing parts arev thoroughly lubricated and protected.

The parts are very simple in form and easily and quickly assembled or disassembled.

Owing to the form and arrangement of the parts they are Iwell calculated to resist the wear and stresses to which they are subjected in use, so 4that the joint can be made 'compact and of comparatively light weight and still prove etlicient and durable.

Having thus described my invention, what I claim as .new and desire'to secure by Letters Patent, is:

l. In a universal joint,'the combination of male and female shaft mcu'ibers, the fe-v male shaft member having a part internally cylindrical, the male member ha ving aspherically curved head, a sphericaily curved annular journal member, said journal member being adapted to oscillatc within said cylindrical economici] to manufacture and are also very part of said female member, said male member-"being adapted to oscillate Within said yjournal"member, 'saidv parts having a Working fit each Within they other, journals for said journal member threaded into said fej male member from the outside, a journal pin forsaid male member disposed through said journal member and said male member head at right langles to the journals of said journal member, and a flexible casing member secured at one end to said-female member and atvthe other -to the shank of said male member.

'2L In a universal joint, thecombination of male and female shaft members, the femaleshaft member constitutingA a casing` member and havinga part internally -cylindrical,fthe male member having a spheri-` vcally curved head,.a spherically curved an-A -nular journal member, said journal member being adapted to oscillate within said I I cylindrical part of saidfemale member', said male member bei-ng adapted` to A'oscillate Within said journal member, saidv parts having` a Working fit each Within the other,`jour n'als for said journal 'member threaded into Said female memberfrom the outside, and

I a journal pin for lsaid male member disposed through said journal member and said male member head at right ,angles to the journals of said journal member.`

3. In a universal joint, the combination of-male and female shaft members,'the fe;

.male shaft member constituting a casing member and having a partinternally cylindrical, the male member havingy a spheriallyy curved head,` sai-d members being adapted to receive the .shafts to'be coupled,

' a spherically curved annular journal mem-4 ber, said journal member'being adapted to oscillate Within said cylindrical part .of

`said female member, said male member being adapted to oscillate Within said journal 'member, vsaid partsi'having a Working fit each Within the other, journals for said journal member threaded in to said vfemale member from the outside, a journal pin for said male member disposed-through said- '0. journal member and said male member head at right angles to the journals of said-journal member, and a block in the head of said male member through which its said journal pin is disposed.

4.`In 'a universal joint, the combination of'male and female shaft members, the fei male member constituting an integral casing member, an annular member journaled Within said. `female member to oscillate therein, said male member having a head disposed within 'said annular vmember yto oscillate therein, journals lfor said annular member member to oscillate therein, journals for` .said annular member threaded intosaid femalel member from ,the outside', and a journal pm for said male member `disposed through said annular'member'andsaid male member headat right angles to the journals of said annular member.

6. In auniversal joint,-the combination of male and female shaft members, the -fe- 'male memberhaving a part internallyv cylin-l drical, an annular journal member disposed within said female member to oscillate there-k in, Vsaid male memberv having a head dis posed within said journal member to oscil late therein, journals for said journal memberthreaded'intosaid female member from the outside, a journal pin for said male member disposed through saidjournal member and saidmale member headat right angles to the journals of said journal member, and

a block in the head of said male member through whichits said journal pin is disposed.

7. In a universalfjoint, the combination of male'and female shaft members, the female member having a. part internally cylindrical, anvann'ular journal member disposed within said cylindrical part ofsaid `female member to'oscillate therein, said male member having a head disposed within said journal member to oscillate therein, a pair of journals for said journal member carried by said female member and removable from the outside thereof, and a journal pin for said male member disposed through said journalmember and said male member head at right angles to the journals of said jour` nal member, said journal pin being retained in said journal member by the Walls of said female member.

In Witness whereof, I have hereunto Set my hand and seal inthe presence of two witnesses.`
